ATLAS/ICESat-2 L3A Sea Ice Height Quick Look, Version 5
ATL07QL is the quick look version of ATL07. Once final ATL07 files are available the corresponding ATL07QL files will be removed.
ATL07 contains along-track heights for sea ice and open water leads (at varying length scales) relative to the WGS84 ellipsoid (ITRF2014 reference frame) after adjustment for geoidal and tidal variations, and inverted barometer effects. Height statistics and apparent reflectance are also provided. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory.
This is the most recent version of these data.
